Mental Health Flashcards
(31 cards)
signs and symptoms of serotonin toxicity
mental: agitation, confusion, delirium
autonomic: diarrhea, sweating, increased temp
neuromuscular: tremor, clonus, hyperreflexia
how do you know serotonin toxicity is severe
temp >38.5
muscle hypertonicity
mild serotonin syndrome
tremor
diarrhea
diagnosis of serotonin syndrome
complete history and clinical presentation
how is NMS diff from ST
immobile
constipation
pallor
no seizures
when does ST present
within 1-24hr of dose increase of drug added
2/3 in 6 hr
3/4 in 24hr
MAOi + serotonin
immediately go to ICU life threatening
SSRI only OD
go to hospital often not life threatening but will worsen
moderate ST
mood elevation
confusion
sweating, mydriasis, increased HR
what to do in mild ST
go see doctor
usually just stop the drug or decrease dose
pathophysiology of ST
drugs that increase production, decrease reuptake, decrease metabolism, increase release
work at the 2A receptors
triptan risk of ST
0.03%
very unlikely because works at different receptors
use of antipyretic in ST?
no bc increased temp due to excessive muscarinic activity rather than the thermoregulatory centre
loperamide in ST?
nope lol also dueto excessive muscarinic activity??
treatment of mild ST
stop offending agent
benzo for agitation and hypertonicity
treatment of moderate ST
benzo - to treat agitation and tremors, prevent rhabdo lactic acidosis, hyperthermia
maybe cyproheptadine
treatment of severe ST
sedation, intubation
active cooling
neuromuscular paralysis
cyproheptadine
what is cyproheptadine
binds to 5HT receptors - antagonist
dosing of cyproheptadine
12mg stat then2mg every 2hr
monitoring for effiacy
symptom resolution
should resolve in 24-72hr in mild-mod
GI and CNS in 3-5day
if not improving or worsening go to hospital
monitoring safety
new med side effects
educate on ST and drugs to avoid
how long for antidepressants to take effect
1-3 for physical symptoms
4-6 for mood
why is suicide increased with antidepressant
increased physical activity but decreased mood
frustration due to delayed onset
antidepressant induced restlessness common in chilldren
duration of antidepressant treatment
at least 6-12month has been shown to decrease relaspse rate
